Etymology: Parachaenichthys: Greek, para = the side of + Greek, chaino = open the mouth (Ref. 45335).
Environment / Climate / Range
Marine; demersal; depth range 5 - 270 m (Ref. 5192). Polar; 53°S - 57°S
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 59.0 cm SL male/unsexed; (Ref. 5192)
Southern Ocean: Insular shelf of South Georgia and Sandwich Islands.
Adults feed on fishes and mysids, Crangon antarcticus and Chorismus antarcticus (Ref. 5192). Spawning from end of summer to early winter and hatching occurs throughout winter. Eggs large, 2.4-3.4 mm in diameter, bright red and benthic (Ref. 5192). Synchronous spawner (Ref. 50743). Larval pelagic phase is long (Ref. 35742).
Oocyte maturation occurs synchronously, thus, spawning is completed in a single occasion (Ref. 50743).

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), based on all LWR estimates (Ref. 93245
Trophic Level (Ref. 69278
): 4.0 ±0.6 se; Based on diet studies.
Resilience (Ref. 69278
): Medium, minimum population doubling time 1.4 - 4.4 years (Fec = 8,585).
Vulnerability (Ref. 59153
